[Haskell-cafe] What ever happened to Haskell 98 as a "stable branch"?

Upon more reflection...

In other words, we already have a stable branch of Haskell.

Why, then, are we so paranoid about introducing breaking changes in
the development branch of haskell?  Why are we stuck without the class
system extension proposal?  Why is Num so still so horribly mangled?
Why can I not 'map' over a Set?  Why must I use lists of characters if
I desire standard sorting?  Why can I not get a good error message
from read? 

(If you answer "because H98 is obsolete", then file this away as a
must-read after H' is released.)
